Ngaba i-methyl seluplose i-seluplose ether?

Intshayelelo kwi-selupese
I-seluplose yenye yezona zinto zibalulekileyo emhlabeni, ezifumaneka kwiindonga zeseli. Yi-Polysaccharide eqokelelwe iiyunithi zeGlucose ephinda-phindwe kunye β (1 → 4) I-Glycosidic. I-Selessulose eves ikhuphe i-selsulose, apho omnye okanye ngaphezulu amaqela e-hydroxyl (--) Ezi ndawo zifake indawo zitshintsha iipropathi zomzimba kunye nekhemikhali ye-seluplose, eyenza ilungele izicelo ezahlukeneyo zeshishini.

I-Methyl Selelose: Ingcaciso kunye neWorpoce:
I-Methyl Selelose sisisele i-Ether Ither ivela kwi-seluplose ngokusebenzisa amaqela e-hydroxyl nge-methyl (-C3) amaqela e-ether. Oku kufaka endaweni yokufaka i-polymer ngokuphucula ukulimala emanzini kunye nezinye iinyikima zepolar xa kuthelekiswa ne-naticade. Inqanaba lokufakwa endaweni (DS) libhekisa kwinani le-hydroxyl amaqela e-methyl ekryl iyunithi nganye kwi-Glulose ye-Glulose ye-Seleyl Selelose.

Isakhiwo sekhemikhali se-methyl seluplose sinokwahluka ngokuxhomekeke kwinqanaba lokufaka endaweni yokufaka endaweni kunye nokusasazwa kwamaqela e-methyl ekrokrisayo kwikhonkco. Ngokubanzi, i-methyl seluplose Molecules i-thelymers eneempawu eziguquguqukayo, zibavumela ukuba benze izisombululo ngeepropathi ezizodwa.

Inkqubo yeMveliso:
I-methyl seluplose iveliswa ngokuthatha i-etherpulose ye-sellyulose ne-methyl chloride okanye i-methyl ye-methyl phambi kwe-alkaline catalysts.
